METHOD OF PRODUCING JOINTLESS MATERIAL FOR COVERING WALLS AND THE LIKE.

No Drawing.

To all whom it may concern:

Be it known that I, .Or'ro FAUSER, manufacturer, peror, and residing at 14 Weinbergerstras'se.

Leipzig-Leutsch, Germany, have invented a certain new and useful Method of Producin Jointless Material for Covering Walls an the Like, of which the following is a specification.

This invention relates to a method of producing jointless material for covering walls and the like. The methods of producing such jointless material for cover1n floors, ceilings, walls and the like employed hitherto have the disadvantage, that as a rule, the hardened material forms blisters and bumps after a short time. Furthermore, the covering materials produced in accordance with the old methods, are notcapable of resistconsiderably affected by cleaning and similar operations. above mentioned is to be attributed to the fact, that the magnesite used as a rule, floors being already more or less carbonic when applied, secretes the carbonic acid after being worked, thus causing the said blisters.

The object of the invention is to prevent the magnesite from secretingcarbonic acid by making suitable counteracting additions. Thus the formation of blisters or the like, is made impossible and a covering material is produced, which remains smooth and level under any circumstances. Moreover by making suitable other additions the result may be obtained that the finished covermg material is capable of resisting acids or soaps.

As base materials for this method materials already known for such urposes such as cork meal or dust, wood 3 saw-dust, stone sand, sand or the like can be used to 45 which also talc may be added.

and subject of the German Em-- ing acids or soaps, so that the materials are The formations of blisters for our or dust, slate dust or flour, ashes, pumice Patented J an. 4, 1910.

Application filed June 15, 1908. Serial No. 438,646.

In order to carry out the process chlorid of magnesium is dissolved in water and at the same. time a mixture of sulfate of zinc, acetic acid and soap made from a fatty body is prepared. The latter mixture is mixed'fio with the chlorid of magnesium solution in suitable pro ortion and the so obtained mass is thoroug y mixed with the above mentioned pulverized materials. The mass is then deposited in the usual manner on the surfaces to be covered and is treated in every other respect ina known manner. It is obvious that in corres onding molds the most varied articles may produced.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A covering material comprlsmg a base material, sulfate of zinc, acetic acld, soap prepared from a fatty body, chlorid of magnesium, and water.

2. A covering material comprising 1n combination, a base material, sulfate of Z1110, acetic acid, soap prepared from a fatty body, chlorid of magnesium and water, combined. 70 to reduce a covering free from swelling K and blisterin and capable of resisting the action dad and soap, such as are used for disinfecting.

3. A recess of preparin covermig mate- 75 rial which consists in disso ving ch orid of magnesium in water, then preparing a mixture of sulfate of zinc, acetic acid and soap pre ared from a fatty body and mixing it wi the chlorid of magnesium solution and 80 then adding a base material.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
